To use a custom cover size in your theme or plugin, simply pass an integer to
PeepSoUser::get_cover($value). Custom sized images are generated on-the-fly and stored in the user’s directory.
If you do use custom cover images by passing an integer to
PeepSoUser::get_cover(), you should hook into this filter to make sure your custom sized cover is deleted when the user removes it.
Let’s say you use a custom sized cover of 666 somewhere in your plugin or theme:
Since PeepSo creates a file on-the-fly if needed, make sure the file is cleaned up when user removes his cover. To do that, you need to add your custom size to the array of integers.
